IMPROVEMENT lN FOLDING CHAIRS.

Specification forming part of Letters Patent No, 179,978, dated July 18,1876; application filed May 18,1876. v

To all whom it may concern:

Be it known that I, EDWARD W. VAILL, of

have invented an Improvement in Folding Chairs, of which the followingis a specification:

This improvement applies to that class of formed in one frame, and thefront legs are pivoted directly to the back legs, as in the patent of P.Born, reissued December 21, 1875.

M y presentinvention consists in the com bination, with the frameforming the back and back legs and the pivoted front legs, of a seatthat is pivoted to the front legs, and links or hinges connecting theseat to the back-frame, whereby the back of the chair-seat is raised andswings upwardly in folding the chair, "and the weight of the seat servesat all times to prevent the chair folding while being used or moved fromplace to place.

In the drawing, Figure 1 is a vertical sec-. tion of the chair in itsfolded position, and Fig. 2 is a similar view with the chair open foruse.

The back legs to extend up to form the backfralne. There arecross-pieces b, forming the back-rests or receiving the upholstery orornamental back. The front legsd extend above legs a, similar to thosein the said Born patent. There may be arm-rests g, if desired.

Instead of the seat being hinged or pivoted to the back legs, as in saidpatent, it is pivoted or hinged to the front legs, or the bar seat, ator near the under side thereof, and

the other ends are connected to the back legs, either directly or by thecross-rail 0.

When the chair is folded the front edge of the seat or seat-frame turnsdownward and the back edge swings upward, and the front legs closeagainst the back legs, as seen'in Fig. 1. v

A latch or catch may be applied at the junction of the back legs andseat, to prevent the chair folding backwardly by pressure upon the frontedge of the seat, as seen'at t, Fig.2.

I claim as my invention-- The seat h, pivoted or hinged to the frontlegs or cross-bar. and the linksl, uniting the seat to the back legs, incombination with the front legs, extending above the seat and connectedto the back legs, substantially as set forth.

Signed by me this 11th day of May, A. D. 1876.
